You say your are having points. But why do the points have an extent?
How have they be generated?
Maybe you can generated polygons - or rectangles - instead of points.
Then you can extract those pixels either by “Raster / Export / Mask Pixels” or you can use the StatisticsOp. There is a thread explaining its usage.
A StatisticsOp graph - GPF Graphs - STEP Forum (esa.int)
If you still want to resample the S2 data you can use the Multi-size Mosaic operator at “Raster / Geometric / Multi-size Mosaic”.
